The BR Series of Butyl liners and septa are manufactured from a high quality, custom formulated compound (BR502) and exhibit excellent low permeability characteristics, very good chemical resistance, and can withstand temperatures up to 100o C. Butyl septa work especially well when in contact with ketones and acids and are most commonly available in 11mm and 20mm aluminum crimp caps, although other configurations are also readily available.
